Hi Paolo, here is v3 of the groundwork patches for the upcoming SEV-ES support in the Linux kernel. They are part of both the client patch-set and the KVM hypervisor patches (under development). Patch 1 necesary to fix a compile warning about a stack-frame getting too large. The other 3 patches define the Guest Hypervisor Communication Block (GHCB) and accessor functions. This version addresses the review comments from Sean. It would be great if you could consider them for v5.9, so that the client and the hypervisor patch-sets can be developed more independently of each other. Please let me know what you think.
